Yes. It is an issue I am going to solve soon (today or tomorrow). It's a 
  problem of compatibility vs jdk's files and directories. I have to 
change some defaults and see if it improves this.

Concerning the other problem with regression tests it is partly ecj's 
fault. It doesn't accept classpaths beginning with ':', though it may 
accept them inside the classpath. I mean:

* CLASSPATH=:somejar:somedirectory is illegal for ecj
* CLASSPATH=somejar::somedirectory is legal for ecj

I will see if I can circumvent this bug.

Guilhem.
